Bronica's budget 645 leaf-shutter SLR — in-lens shutters, ETR lenses, 1978.
The Bronica ETRC is a late-1970s medium-format SLR, a variant of the ETR in Zenza Bronica's 6x4.5 leaf-shutter system. It was offered as a lower-cost option with a fixed rather than fully removable film back, making it a simpler entry into the ETR line while keeping the same lenses and finders.
It is a medium-format (6x4.5) SLR shooting a 56x42mm frame on 120 or 220 film. It uses leaf shutters built into the ETR lenses, giving flash sync at all speeds, and is electronically controlled. The body takes interchangeable waist-level or prism finders and focusing screens and mounts Bronica ETR bayonet lenses; a metered prism can provide TTL metering, while the plain body has no meter.
The ETRC suited photographers and students who wanted the ETR lens system and 645 frame at a lower cost and did not need mid-roll film-back swaps. With a metered prism it handles like a large SLR and works for portrait and general medium-format photography.
Confirm the electronic body fires on a fresh battery. Test each lens leaf shutter for accurate speeds, check the film back and its seals along with the dark slide, and inspect the mirror, screen, and finder mirror. Foam light seals commonly perish on bodies of this age and should be verified before buying.
